FIELD OF THE INVENTION

Described herein are compounds, methods of making such compounds,pharmaceutical compositions and medicaments containing such compounds,and methods of using such compounds and compositions to inhibit theactivity of tyrosine kinases.

BACKGROUND OF THE INVENTION

Bruton's tyrosine kinase (Btk), a member of the Tec family ofnon-receptor tyrosine kinases, is a key signaling enzyme expressed inall hematopoietic cells types except T lymphocytes and natural killercells. Btk plays an essential role in the B-cell signaling pathwaylinking cell surface B-cell receptor (BCR) stimulation to downstreamintracellular responses.

Btk is a key regulator of B-cell development, activation, signaling, andsurvival (Kurosaki, Curr Op Imm, 2000, 276-281; Schaeffer andSchwartzberg, Curr Op Imm 2000, 282-288). In addition, Btk plays a rolein a number of other hematopoetic cell signaling pathways, e.g., Tolllike receptor (TLR) and cytokine receptormediated TNF-α production inmacrophages, IgE receptor (FcepsilonRI) signaling in Mast cells,inhibition of Fas/APO-1 apoptotic signaling in B-lineage lymphoid cells,and collagen-stimulated platelet aggregation.

DETAILED DESCRIPTION OF THE INVENTION

The methods described herein include administering to a subject in needa composition containing a therapeutically effective amount of one ormore reversible or irreversible Btk inhibitor compounds describedherein. Without being bound by theory, the diverse roles played by Btksignaling in various hematopoietic cell functions, e.g., B-cell receptoractivation, suggests that small molecule Btk inhibitors are useful forreducing the risk of or treating a variety of diseases affected by oraffecting many cell types of the hematopoetic lineage including, e.g.,autoimmune diseases, heteroimmune conditions or diseases, inflammatorydiseases, cancer (e.g., B-cell proliferative disorders), andthromboembolic disorders.

Symptoms, diagnostic tests, and prognostic tests for each of theabove-mentioned conditions are known in the art. See, e.g., Harrison'sPrinciples of Internal Medicine©” 16th ed., 2004, The McGraw-HillCompanies, Inc. Dey et al. (2006), Cytojournal 3(24), and the “RevisedEuropean American Lymphoma” (REAL) classification system (see, e.g., thewebsite maintained by the National Cancer Institute).

A number of animal models of are useful for establishing a range oftherapeutically effective doses of reversible or irreversible Btkinhibitor compounds for treating any of the foregoing diseases.

For example, dosing of reversible or irreversible Btk inhibitorcompounds for treating an autoimmune disease can be assessed in a mousemodel of rheumatoid arthritis. In this model, arthritis is induced inBalb/c mice by administering anti-collagen antibodies andlipopolysaccharide. See Nandakumar et al. (2003), Am. J. Pathol163:1827-1837.

In another example, dosing of reversible or irreversible Btk inhibitorsfor the treatment of B-cell proliferative disorders can be examined in,e.g., a human-to-mouse xenograft model in which human B-cell lymphomacells (e.g. Ramos cells) are implanted into immunodeficient mice (e.g.,“nude” mice) as described in, e.g., Pagel et al. (2005), Clin Cancer Res11(13):4857-4866.

Animal models for treatment of thromboembolic disorders are also known.

The therapeutic efficacy of the compound for one of the foregoingdiseases can be optimized during a course of treatment. For example, asubject being treated can undergo a diagnostic evaluation to correlatethe relief of disease symptoms or pathologies to inhibition of in vivoBtk activity achieved by administering a given dose of an irreversibleBtk inhibitor. Cellular assays known in the art can be used to determinein vivo activity of Btk in the presence or absence of an irreversibleBtk inhibitor. For example, since activated Btk is phosphorylated attyrosine 223 (Y223) and tyrosine 551 (Y551), phospho-specificimmunocytochemical staining of P-Y223 or P-Y551-positive cells can beused to detect or quantify activation of Bkt in a population of cells(e.g., by FACS analysis of stained vs unstained cells). See, e.g.,Nisitani et al. (1999), Proc. Natl. Acad. Sci, USA 96:2221-2226. Thus,the amount of the Btk inhibitor compound that is administered to asubject can be increased or decreased as needed so as to maintain alevel of Btk inhibition optimal for treating the subject's diseasestate.

Compounds

In the following description of reversible or irreversible Btk compoundssuitable for use in the methods described herein, definitions ofreferred-to standard chemistry terms may be found in reference works (ifnot otherwise defined herein), including Carey and Sundberg “AdvancedOrganic Chemistry 4th Ed.” Vols. A (2000) and B (2001), Plenum Press,New York. Unless otherwise indicated, conventional methods of massspectroscopy, NMR, HPLC, protein chemistry, biochemistry, recombinantDNA techniques and pharmacology, within the ordinary skill of the artare employed. In addition, nucleic acid and amino acid sequences for Btk(e.g., human Btk) are known in the art as disclosed in, e.g., U.S. Pat.No. 6,326,469. Unless specific definitions are provided, thenomenclature employed in connection with, and the laboratory proceduresand techniques of, analytical chemistry, synthetic organic chemistry,and medicinal and pharmaceutical chemistry described herein are thoseknown in the art. Standard techniques can be used for chemicalsyntheses, chemical analyses, pharmaceutical preparation, formulation,and delivery, and treatment of patients.

The Btk inhibitor compounds described herein are selective for Btk andkinases having a cysteine residue in an amino acid sequence position ofthe tyrosine kinase that is homologous to the amino acid sequenceposition of cysteine 481 in Btk Inhibitor compounds described hereininclude a Michael acceptor moiety.

Generally, a reversible or irreversible inhibitor compound of Btk usedin the methods described herein is identified or characterized in an invitro assay, e.g., an acellular biochemical assay or a cellularfunctional assay. Such assays are useful to determine an in vitro IC₅₀for a reversible or irreversible Btk inhibitor compound.

For example, an acellular kinase assay can be used to determine Btkactivity after incubation of the kinase in the absence or presence of arange of concentrations of a candidate irreversible Btk inhibitorcompound. If the candidate compound is in fact an irreversible Btkinhibitor, Btk kinase activity will not be recovered by repeat washingwith inhibitor-free medium. See, e.g., J. B. Smaill, et al. (1999), J.Med. Chem. 42(10):1803-1815. Further, covalent complex formation betweenBtk and a candidate irreversible Btk inhibitor is a useful indicator ofirreversible inhibition of Btk that can be readily determined by anumber of methods known in the art (e.g., mass spectrometry). Forexample, some irreversible Btk-inhibitor compounds can form a covalentbond with Cys 481 of Btk (e.g., via a Michael reaction).

Cellular functional assays for Btk inhibition include measuring one ormore cellular endpoints in response to stimulating a Btk-mediatedpathway in a cell line (e.g., BCR activation in Ramos cells) in theabsence or presence of a range of concentrations of a candidateirreversible Btk inhibitor compound. Useful endpoints for determining aresponse to BCR activation include, e.g., autophosphorylation of Btk,phosphorylation of a Btk target protein (e.g., PLC-γ), and cytoplasmiccalcium flux.

High throughput assays for many acellular biochemical assays (e.g.,kinase assays) and cellular functional assays (e.g., calcium flux) arewell known to those of ordinary skill in the art. In addition, highthroughput screening systems are commercially available (see, e.g.,Zymark Corp., Hopkinton, Mass.; Air Technical Industries, Mentor, Ohio;Beckman Instruments, Inc. Fullerton, Calif.; Precision Systems, Inc.,Natick, Mass., etc.). These systems typically automate entire proceduresincluding all sample and reagent pipetting, liquid dispensing, timedincubations, and final readings of the microplate in detector(s)appropriate for the assay. Automated systems thereby allow theidentification and characterization of a large number of reversible orirreversible Btk compounds without undue effort.

Reversible or irreversible Btk inhibitor compounds can be used for themanufacture of a medicament for treating any of the foregoing conditions(e.g., autoimmune diseases, inflammatory diseases, allergy disorders,B-cell proliferative disorders, or thromboembolic disorders).

In some embodiments, the reversible or irreversible Btk inhibitorcompound used for the methods described herein inhibits Btk or a Btkhomolog kinase activity with an in vitro IC₅₀ of less than about 10 μM.(e.g., less than about 1 μM, less than about 0.5 μM, less than about 0.4μM, less than about 0.3 μM, less than about 0.1, less than about 0.08μM, less than about 0.06 μM, less than about 0.05 μM, less than about0.04 μM, less than about 0.03 μM, less than about 0.02 μM, less thanabout 0.01, less than about 0.008 μM, less than about 0.006 μM, lessthan about 0.005 μM, less than about 0.004 μM, less than about 0.003 μM,less than about 0.002 μM, less than about 0.001, less than about 0.00099μM, less than about 0.00098 μM, less than about 0.00097 μM, less thanabout 0.00096 μM, less than about 0.00095 μM, less than about 0.00094μM, less than about 0.00093 μM, less than about 0.00092, or less thanabout 0.00090 μM).

In one embodiment, the irreversible Btk inhibitor compound selectivelyand irreversibly inhibits an activated form of its target tyrosinekinase (e.g., a phosphorylated form of the tyrosine kinase). Forexample, activated Btk is transphosphorylated at tyrosine 551. Thus, inthese embodiments the irreversible Btk inhibitor inhibits the targetkinase in cells only once the target kinase is activated by thesignaling events.

Further Forms of Compounds

Compounds disclosed herein have a structure of Formula (IA), (I), (Ia),(II), (III), (IV), (Va)-(Vh), or (VIa)-(VIb). It is understood that whenreference is made to compounds described herein, it is meant to includecompounds of any of Formula (IA), (I), (Ia), (II), (III), (IV),(Va)-(Vh), or (VIa)-(VIb), as well as to all of the specific compoundsthat fall within the scope of these generic formulae, unless otherwiseindicated.

The compounds described herein may possess one or more stereocenters andeach center may exist in the R or S configuration. The compoundspresented herein include all diastereomeric, enantiomeric, and epimericforms as well as the appropriate mixtures thereof. Stereoisomers may beobtained, if desired, by methods known in the art as, for example, theseparation of stereoisomers by chiral chromatographic columns.

Diasteromeric mixtures can be separated into their individualdiastereomers on the basis of their physical chemical differences bymethods known, for example, by chromatography and/or fractionalcrystallization. In one embodiment, enantiomers can be separated bychiral chromatographic columns. In other embodiments, enantiomers can beseparated by converting the enantiomeric mixture into a diastereomericmixture by reaction with an appropriate optically active compound (e.g.,alcohol), separating the diastereomers and converting (e.g.,hydrolyzing) the individual diastereomers to the corresponding pureenantiomers. All such isomers, including diastereomers, enantiomers, andmixtures thereof are considered as part of the compositions describedherein.

The methods and formulations described herein include the use ofN-oxides, crystalline forms (also known as polymorphs), orpharmaceutically acceptable salts of compounds described herein, as wellas active metabolites of these compounds having the same type ofactivity. In some situations, compounds may exist as tautomers. Alltautomers are included within the scope of the compounds presentedherein. In addition, the compounds described herein can exist inunsolvated as well as solvated forms with pharmaceutically acceptablesolvents such as water, ethanol, and the like. The solvated forms of thecompounds presented herein are also considered to be disclosed herein.

Compounds of any of Formula (IA), (I), (Ia), (II), (III), (IV),(Va)-(Vh), or (VIa)-(VIb) in unoxidized form can be prepared fromN-oxides of compounds of any of Formula (IA), (I), (Ia), (II), (III),(IV), (Va)-(Vh), or (VIa)-(VIb) by treating with a reducing agent, suchas, but not limited to, sulfur, sulfur dioxide, triphenyl phosphine,lithium borohydride, sodium borohydride, phosphorus trichloride,tribromide, or the like in a suitable inert organic solvent, such as,but not limited to, acetonitrile, ethanol, aqueous dioxane, or the likeat 0 to 80° C.

In some embodiments, compounds described herein are prepared asprodrugs. A “prodrug” refers to an agent that is converted into theparent drug in vivo. Prodrugs are often useful because, in somesituations, they may be easier to administer than the parent drug. Theymay, for instance, be bioavailable by oral administration whereas theparent is not. The prodrug may also have improved solubility inpharmaceutical compositions over the parent drug. An example, withoutlimitation, of a prodrug would be a compound described herein, which isadministered as an ester (the “prodrug”) to facilitate transmittalacross a cell membrane where water solubility is detrimental to mobilitybut which then is metabolically hydrolyzed to the carboxylic acid, theactive entity, once inside the cell where water-solubility isbeneficial. A further example of a prodrug might be a short peptide(polyaminoacid) bonded to an acid group where the peptide is metabolizedto reveal the active moiety. In certain embodiments, upon in vivoadministration, a prodrug is chemically converted to the biologically,pharmaceutically or therapeutically active form of the compound. Incertain embodiments, a prodrug is enzymatically metabolized by one ormore steps or processes to the biologically, pharmaceutically ortherapeutically active form of the compound. To produce a prodrug, apharmaceutically active compound is modified such that the activecompound will be regenerated upon in vivo administration. The prodrugcan be designed to alter the metabolic stability or the transportcharacteristics of a drug, to mask side effects or toxicity, to improvethe flavor of a drug or to alter other characteristics or properties ofa drug. By virtue of knowledge of pharmacodynamic processes and drugmetabolism in vivo, those of skill in this art, once a pharmaceuticallyactive compound is known, can design prodrugs of the compound. (see, forexample, Nogrady (1985) Medicinal Chemistry A Biochemical Approach,Oxford University Press, New York, pages 388-392; Silverman (1992), TheOrganic Chemistry of Drug Design and Drug Action, Academic Press, Inc.,San Diego, pages 352-401, Saulnier et al., (1994), Bioorganic andMedicinal Chemistry Letters, Vol. 4, p. 1985).

Prodrug forms of the herein described compounds, wherein the prodrug ismetabolized in vivo to produce a derivative as set forth herein areincluded within the scope of the claims. In some cases, some of theherein-described compounds may be a prodrug for another derivative oractive compound.

Prodrugs are often useful because, in some situations, they may beeasier to administer than the parent drug. They may, for instance, bebioavailable by oral administration whereas the parent is not. Theprodrug may also have improved solubility in pharmaceutical compositionsover the parent drug. Prodrugs may be designed as reversible drugderivatives, for use as modifiers to enhance drug transport tosite-specific tissues. In some embodiments, the design of a prodrugincreases the effective water solubility. See, e.g., Fedorak et al., Am.J. Physiol., 269:G210-218 (1995); McLoed et al., Gastroenterol,106:405-413 (1994); Hochhaus et al., Biomed. Chrom., 6:283-286 (1992);J. Larsen and H. Bundgaard, Int. J.

Additionally,pharmaceutical formulations described herein may be administered as asingle capsule or in multiple capsule dosage form. In some embodiments,the pharmaceutical formulation is administered in two, or three, orfour, capsules or tablets.

In some embodiments, solid dosage forms, e.g., tablets, effervescenttablets, and capsules, are prepared by mixing particles of a compound ofany of Formula (IA), (I), (Ia), (II), (III), (IV), (Va)-(Vh), or(VIa)-(VIb), with one or more pharmaceutical excipients to form a bulkblend composition. When referring to these bulk blend compositions ashomogeneous, it is meant that the particles of the compound of any ofFormula (IA), (I), (Ia), (II), (III), (IV), (Va)-(Vh), or (VIa)-(VIb),are dispersed evenly throughout the composition so that the compositionmay be readily subdivided into equally effective unit dosage forms, suchas tablets, pills, and capsules. The individual unit dosages may alsoinclude film coatings, which disintegrate upon oral ingestion or uponcontact with diluent. These formulations can be manufactured byconventional pharmacological techniques.

Conventional pharmacological techniques include, e.g., one or acombination of methods: (1) dry mixing, (2) direct compression, (3)milling, (4) dry or non-aqueous granulation, (5) wet granulation, or (6)fusion. See, e.g., Lachman et al., The Theory and Practice of IndustrialPharmacy (1986).

Furthermore, other methods such asroller compaction, extrusion/spheronization, coacervation, ornanoparticle coating may also be used.

In one embodiment, the particles of compounds of any of Formula (IA),(I), (Ia), (II), (III), (IV), (Va)-(Vh), or (VIa)-(VIb), aremicroencapsulated prior to being formulated into one of the above forms.In still another embodiment, some or most of the particles are coatedprior to being further formulated by using standard coating procedures,such as those described in Remington's Pharmaceutical Sciences, 20thEdition (2000).

In other embodiments, the solid dosage formulations of the compounds ofany of Formula (IA), (I), (Ia), (II), (III), (IV), (Va)-(Vh), or(VIa)-(VIb), are plasticized (coated) with one or more layers.Illustratively, a plasticizer is generally a high boiling point solid orliquid.

In other embodiments, a powder including the formulations with acompound of any of Formula (IA), (I), (Ia), (II), (III), (IV),(Va)-(Vh), or (VIa)-(VIb), described herein, may be formulated toinclude one or more pharmaceutical excipients and flavors. Such a powdermay be prepared, for example, by mixing the formulation and optionalpharmaceutical excipients to form a bulk blend composition. Additionalembodiments also include a suspending agent and/or a wetting agent. Thisbulk blend is uniformly subdivided into unit dosage packaging ormulti-dosage packaging units.

In still other embodiments, effervescent powders are also prepared inaccordance with the present disclosure. Effervescent salts have beenused to disperse medicines in water for oral administration.Effervescent salts are granules or coarse powders containing a medicinalagent in a dry mixture, usually composed of sodium bicarbonate, citricacid and/or tartaric acid. When salts of the compositions describedherein are added to water, the acids and the base react to liberatecarbon dioxide gas, thereby causing “effervescence.” Examples ofeffervescent salts include, e.g., the following ingredients: sodiumbicarbonate or a mixture of sodium bicarbonate and sodium carbonate,citric acid and/or tartaric acid. Any acid-base combination that resultsin the liberation of carbon dioxide can be used in place of thecombination of sodium bicarbonate and citric and tartaric acids, as longas the ingredients were suitable for pharmaceutical use and result in apH of about 6.0 or higher.

In other embodiments, the formulations described herein, which include acompound of Formula (IA), (I), (Ia), (II), (III), (IV), (Va)-(Vh), or(VIa)-(VIb), are solid dispersions. Methods of producing such soliddispersions are known in the art and include, but are not limited to,for example, U.S. Pat. Nos. 4,343,789, 5,340,591, 5,456,923, 5,700,485,5,723,269, and U.S. Pub. Appl 2004/0013734, each of which isspecifically incorporated by reference. In still other embodiments, theformulations described herein are solid solutions. Solid solutionsincorporate a substance together with the active agent and otherexcipients such that heating the mixture results in dissolution of thedrug and the resulting composition is then cooled to provide a solidblend which can be further formulated or directly added to a capsule orcompressed into a tablet. Methods of producing such solid solutions areknown in the art and include, but are not limited to, for example, U.S.Pat. Nos. 4,151,273, 5,281,420, and 6,083,518, each of which isspecifically incorporated by reference.

The pharmaceutical solid oral dosage forms including formulationsdescribed herein, which include a compound of any of Formula (IA), (I),(Ia), (II), (III), (IV), (Va)-(Vh), or (VIa)-(VIb), can be furtherformulated to provide a controlled release of the compound of Formula(IA), (I), (Ia), (II), (III), (IV), (Va)-(Vh), or (VIa)-(VIb).Controlled release refers to the release of the compound of any ofFormula (IA), (I), (Ia), (II), (III), (IV), (Va)-(Vh), or (VIa)-(VIb),from a dosage form in which it is incorporated according to a desiredprofile over an extended period of time. Controlled release profilesinclude, for example, sustained release, prolonged release, pulsatilerelease, and delayed release profiles. In contrast to immediate releasecompositions, controlled release compositions allow delivery of an agentto a subject over an extended period of time according to apredetermined profile. Such release rates can provide therapeuticallyeffective levels of agent for an extended period of time and therebyprovide a longer period of pharmacologic response while minimizing sideeffects as compared to conventional rapid release dosage forms. Suchlonger periods of response provide for many inherent benefits that arenot achieved with the corresponding short acting, immediate releasepreparations.

In some embodiments, the solid dosage forms described herein can beformulated as enteric coated delayed release oral dosage forms, i.e., asan oral dosage form of a pharmaceutical composition as described hereinwhich utilizes an enteric coating to affect release in the smallintestine of the gastrointestinal tract. The enteric coated dosage formmay be a compressed or molded or extruded tablet/mold (coated oruncoated) containing granules, powder, pellets, beads or particles ofthe active ingredient and/or other composition components, which arethemselves coated or uncoated. The enteric coated oral dosage form mayalso be a capsule (coated or uncoated) containing pellets, beads orgranules of the solid carrier or the composition, which are themselvescoated or uncoated.

The term “delayed release” as used herein refers to the delivery so thatthe release can be accomplished at some generally predictable locationin the intestinal tract more distal to that which would have beenaccomplished if there had been no delayed release alterations. In someembodiments the method for delay of release is coating. Any coatingsshould be applied to a sufficient thickness such that the entire coatingdoes not dissolve in the gastrointestinal fluids at pH below about 5,but does dissolve at pH about 5 and above. It is expected that anyanionic polymer exhibiting a pH-dependent solubility profile can be usedas an enteric coating in the methods and compositions described hereinto achieve delivery to the lower gastrointestinal tract. In someembodiments the polymers described herein are anionic carboxylicpolymers. In other embodiments, the polymers and compatible mixturesthereof, and some of their properties, include, but are not limited to:

Shellac, also called purified lac, a refined product obtained from theresinous secretion of an insect. This coating dissolves in media ofpH>7;

Acrylic polymers. The performance of acrylic polymers (primarily theirsolubility in biological fluids) can vary based on the degree and typeof substitution. Examples of suitable acrylic polymers includemethacrylic acid copolymers and ammonium methacrylate copolymers. TheEudragit series E, L, S, RL, RS and NE (Rohm Pharma) are available assolubilized in organic solvent, aqueous dispersion, or dry powders. TheEudragit series RL, NE, and RS are insoluble in the gastrointestinaltract but are permeable and are used primarily for colonic targeting.The Eudragit series E dissolve in the stomach. The Eudragit series L,L-30D and S are insoluble in stomach and dissolve in the intestine;

Cellulose Derivatives. Examples of suitable cellulose derivatives are:ethyl cellulose; reaction mixtures of partial acetate esters ofcellulose with phthalic anhydride. The performance can vary based on thedegree and type of substitution. Cellulose acetate phthalate (CAP)dissolves in pH>6. Aquateric (FMC) is an aqueous based system and is aspray dried CAP psuedolatex with particles <1 μm. Other components inAquateric can include pluronics, Tweens, and acetylated monoglycerides.Other suitable cellulose derivatives include: cellulose acetatetrimellitate (Eastman); methylcellulose (Pharmacoat, Methocel);hydroxypropylmethyl cellulose phthalate (HPMCP); hydroxypropylmethylcellulose succinate (HPMCS); and hydroxypropylmethylcellulose acetatesuccinate (e.g., AQOAT (Shin Etsu)). The performance can vary based onthe degree and type of substitution. For example, HPMCP such as, HP-50,HP-55, HP-55S, HP-55F grades are suitable. The performance can varybased on the degree and type of substitution. For example, suitablegrades of hydroxypropylmethylcellulose acetate succinate include, butare not limited to, AS-LG (LF), which dissolves at pH 5, AS-MG (MF),which dissolves at pH 5.5, and AS-HG (HF), which dissolves at higher pH.These polymers are offered as granules, or as fine powders for aqueousdispersions;

Poly Vinyl Acetate Phthalate (PVAP). PVAP dissolves in pH>5, and it ismuch less permeable to water vapor and gastric fluids.

In some embodiments, the coating can, and usually does, contain aplasticizer and possibly other coating excipients such as colorants,talc, and/or magnesium stearate, which are well known in the art.Suitable plasticizers include triethyl citrate (Citroflex 2), triacetin(glyceryl triacetate), acetyl triethyl citrate (Citroflec A2), Carbowax400 (polyethylene glycol 400), diethyl phthalate, tributyl citrate,acetylated monoglycerides, glycerol, fatty acid esters, propyleneglycol, and dibutyl phthalate. In particular, anionic carboxylic acrylicpolymers usually will contain 10-25% by weight of a plasticizer,especially dibutyl phthalate, polyethylene glycol, triethyl citrate andtriacetin. Conventional coating techniques such as spray or pan coatingare employed to apply coatings. The coating thickness must be sufficientto ensure that the oral dosage form remains intact until the desiredsite of topical delivery in the intestinal tract is reached.

Colorants, detackifiers, surfactants, antifoaming agents, lubricants(e.g., carnuba wax or PEG) may be added to the coatings besidesplasticizers to solubilize or disperse the coating material, and toimprove coating performance and the coated product.

In other embodiments, the formulations described herein, which include acompound of Formula (IA), (I), (Ia), (II), (III), (IV), (Va)-(Vh), or(VIa)-(VIb), are delivered using a pulsatile dosage form. A pulsatiledosage form is capable of providing one or more immediate release pulsesat predetermined time points after a controlled lag time or at specificsites. Pulsatile dosage forms including the formulations describedherein, which include a compound of any of Formula (IA), (I), (Ia),(II), (III), (IV), (Va)-(Vh), or (VIa)-(VIb), may be administered usinga variety of pulsatile formulations known in the art. For example, suchformulations include, but are not limited to, those described in U.S.Pat. Nos. 5,011,692, 5,017,381, 5,229,135, and 5,840,329, each of whichis specifically incorporated by reference. Other pulsatile releasedosage forms suitable for use with the present formulations include, butare not limited to, for example, U.S. Pat. Nos. 4,871,549, 5,260,068,5,260,069, 5,508,040, 5,567,441 and 5,837,284, all of which arespecifically incorporated by reference. In one embodiment, thecontrolled release dosage form is pulsatile release solid oral dosageform including at least two groups of particles, (i.e. multiparticulate)each containing the formulation described herein. The first group ofparticles provides a substantially immediate dose of the compound of anyof Formula (IA), (I), (Ia), (II), (III), (IV), (Va)-(Vh), or(VIa)-(VIb), upon ingestion by a mammal. The first group of particlescan be either uncoated or include a coating and/or sealant. The secondgroup of particles includes coated particles, which includes from about2% to about 75%, from about 2.5% to about 70%, or from about 40% toabout 70%, by weight of the total dose of the compound of any of Formula(IA), (I), (Ia), (II), (III), (IV), (Va)-(Vh), or (VIa)-(VIb), in saidformulation, in admixture with one or more binders. The coating includesa pharmaceutically acceptable ingredient in an amount sufficient toprovide a delay of from about 2 hours to about 7 hours followingingestion before release of the second dose.

In some embodiments, the pharmaceutical formulations described hereincan be self-emulsifying drug delivery systems (SEDDS). Emulsions aredispersions of one immiscible phase in another, usually in the form ofdroplets. Generally, emulsions are created by vigorous mechanicaldispersion. SEDDS, as opposed to emulsions or microemulsions,spontaneously form emulsions when added to an excess of water withoutany external mechanical dispersion or agitation. An advantage of SEDDSis that only gentle mixing is required to distribute the dropletsthroughout the solution. Additionally, water or the aqueous phase can beadded just prior to administration, which ensures stability of anunstable or hydrophobic active ingredient. Thus, the SEDDS provides aneffective delivery system for oral and parenteral delivery ofhydrophobic active ingredients. SEDDS may provide improvements in thebioavailability of hydrophobic active ingredients. Methods of producingself-emulsifying dosage forms are known in the art and include, but arenot limited to, for example, U.S. Pat. Nos. 5,858,401, 6,667,048, and6,960,563, each of which is specifically incorporated by reference.

It is to be appreciated that there is overlap between the above-listedadditives used in the aqueous dispersions or suspensions describedherein, since a given additive is often classified differently bydifferent practitioners in the field, or is commonly used for any ofseveral different functions. Thus, the above-listed additives should betaken as merely exemplary, and not limiting, of the types of additivesthat can be included in formulations described herein. The amounts ofsuch additives can be readily determined by one skilled in the art,according to the particular properties desired.

Intranasal Formulations

Intranasal formulations are known in the art and are described in, forexample, U.S. Pat. Nos. 4,476,116, 5,116,817 and 6,391,452, each ofwhich is specifically incorporated by reference. Formulations thatinclude a compound of any of Formula (IA), (I), (Ia), (II), (III), (IV),(Va)-(Vh), or (VIa)-(VIb), which are prepared according to these andother techniques well-known in the art are prepared as solutions insaline, employing benzyl alcohol or other suitable preservatives,fluorocarbons, and/or other solubilizing or dispersing agents known inthe art. See, for example, Ansel, H. C. et al., Pharmaceutical DosageForms and Drug Delivery Systems, Sixth Ed. (1995). Preferably thesecompositions and formulations are prepared with suitable nontoxicpharmaceutically acceptable ingredients. These ingredients are known tothose skilled in the preparation of nasal dosage forms and some of thesecan be found in REMINGTON: THE SCIENCE AND PRACTICE OF PHARMACY, 21stedition, 2005, a standard reference in the field. The choice of suitablecarriers is highly dependent upon the exact nature of the nasal dosageform desired, e.g., solutions, suspensions, ointments, or gels. Nasaldosage forms generally contain large amounts of water in addition to theactive ingredient. Minor amounts of other ingredients such as pHadjusters, emulsifiers or dispersing agents, preservatives, surfactants,gelling agents, or buffering and other stabilizing and solubilizingagents may also be present. The nasal dosage form should be isotonicwith nasal secretions.

For administration by inhalation, the compounds of any of Formula (IA),(I), (Ia), (II), (III), (IV), (Va)-(Vh), or (VIa)-(VIb), describedherein may be in a form as an aerosol, a mist or a powder.Pharmaceutical compositions described herein are conveniently deliveredin the form of an aerosol spray presentation from pressurized packs or anebuliser, with the use of a suitable propellant, e.g.,dichlorodifluoromethane, trichlorofluoromethane,dichlorotetrafluoroethane, carbon dioxide or other suitable gas. In thecase of a pressurized aerosol, the dosage unit may be determined byproviding a valve to deliver a metered amount. Capsules and cartridgesof, such as, by way of example only, gelatin for use in an inhaler orinsufflator may be formulated containing a powder mix of the compounddescribed herein and a suitable powder base such as lactose or starch.

Buccal Formulations

Buccal formulations that include compounds of any of Formula (IA), (I),(Ia), (II), (III), (IV), (Va)-(Vh), or (VIa)-(VIb), may be administeredusing a variety of formulations known in the art. For example, suchformulations include, but are not limited to, U.S. Pat. Nos. 4,229,447,4,596,795, 4,755,386, and 5,739,136, each of which is specificallyincorporated by reference. In addition, the buccal dosage formsdescribed herein can further include a bioerodible (hydrolysable)polymeric carrier that also serves to adhere the dosage form to thebuccal mucosa. The buccal dosage form is fabricated so as to erodegradually over a predetermined time period, wherein the delivery of thecompound of any of Formula (IA), (I), (Ia), (II), (III), (IV),(Va)-(Vh), or (VIa)-(VIb), is provided essentially throughout. Buccaldrug delivery, as will be appreciated by those skilled in the art,avoids the disadvantages encountered with oral drug administration,e.g., slow absorption, degradation of the active agent by fluids presentin the gastrointestinal tract and/or first-pass inactivation in theliver. With regard to the bioerodible (hydrolysable) polymeric carrier,it will be appreciated that virtually any such carrier can be used, solong as the desired drug release profile is not compromised, and thecarrier is compatible with the compound of any of Formula (IA), (I),(Ia), (II), (III), (IV), (Va)-(Vh), or (VIa)-(VIb), and any othercomponents that may be present in the buccal dosage unit. Generally, thepolymeric carrier comprises hydrophilic (water-soluble andwater-swellable) polymers that adhere to the wet surface of the buccalmucosa. Examples of polymeric carriers useful herein include acrylicacid polymers and co, e.g., those known as “carbomers” (Carbopol®, whichmay be obtained from B.F. Goodrich, is one such polymer). Othercomponents may also be incorporated into the buccal dosage formsdescribed herein include, but are not limited to, disintegrants,diluents, binders, lubricants, flavoring, colorants, preservatives, andthe like. For buccal or sublingual administration, the compositions maytake the form of tablets, lozenges, or gels formulated in a conventionalmanner.

Transdermal Formulations

Transdermal formulations described herein may be administered using avariety of devices which have been described in the art. For example,such devices include, but are not limited to, U.S. Pat. Nos. 3,598,122,3,598,123, 3,710,795, 3,731,683, 3,742,951, 3,814,097, 3,921,636,3,972,995, 3,993,072, 3,993,073, 3,996,934, 4,031,894, 4,060,084,4,069,307, 4,077,407, 4,201,211, 4,230,105, 4,292,299, 4,292,303,5,336,168, 5,665,378, 5,837,280, 5,869,090, 6,923,983, 6,929,801 and6,946,144, each of which is specifically incorporated by reference inits entirety.

The transdermal dosage forms described herein may incorporate certainpharmaceutically acceptable excipients which are conventional in theart. In one embodiments, the transdermal formulations described hereininclude at least three components: (1) a formulation of a compound ofany of Formula (IA), (I), (Ia), (II), (III), (IV), (Va)-(Vh), or(VIa)-(VIb); (2) a penetration enhancer; and (3) an aqueous adjuvant. Inaddition, transdermal formulations can include additional componentssuch as, but not limited to, gelling agents, creams and ointment bases,and the like. In some embodiments, the transdermal formulation canfurther include a woven or non-woven backing material to enhanceabsorption and prevent the removal of the transdermal formulation fromthe skin. In other embodiments, the transdermal formulations describedherein can maintain a saturated or supersaturated state to promotediffusion into the skin.

Formulations suitable for transdermal administration of compoundsdescribed herein may employ transdermal delivery devices and transdermaldelivery patches and can be lipophilic emulsions or buffered, aqueoussolutions, dissolved and/or dispersed in a polymer or an adhesive. Suchpatches may be constructed for continuous, pulsatile, or on demanddelivery of pharmaceutical agents. Still further, transdermal deliveryof the compounds described herein can be accomplished by means ofiontophoretic patches and the like. Additionally, transdermal patchescan provide controlled delivery of the compounds of any of Formula (IA),(I), (Ia), (II), (III), (IV), (Va)-(Vh), or (VIa)-(VIb). The rate ofabsorption can be slowed by using rate-controlling membranes or bytrapping the compound within a polymer matrix or gel. Conversely,absorption enhancers can be used to increase absorption. An absorptionenhancer or carrier can include absorbable pharmaceutically acceptablesolvents to assist passage through the skin. For example, transdermaldevices are in the form of a bandage comprising a backing member, areservoir containing the compound optionally with carriers, optionally arate controlling barrier to deliver the compound to the skin of the hostat a controlled and predetermined rate over a prolonged period of time,and means to secure the device to the skin.

Injectable Formulations

Formulations that include a compound of any of Formula (IA), (I), (Ia),(II), (III), (IV), (Va)-(Vh), or (VIa)-(VIb), suitable forintramuscular, subcutaneous, or intravenous injection may includephysiologically acceptable sterile aqueous or non-aqueous solutions,dispersions, suspensions or emulsions, and sterile powders forreconstitution into sterile injectable solutions or dispersions.Examples of suitable aqueous and non-aqueous carriers, diluents,solvents, or vehicles including water, ethanol, polyols(propyleneglycol, polyethylene-glycol, glycerol, cremophor and thelike), suitable mixtures thereof, vegetable oils (such as olive oil) andinjectable organic esters such as ethyl oleate. Proper fluidity can bemaintained, for example, by the use of a coating such as lecithin, bythe maintenance of the required particle size in the case ofdispersions, and by the use of surfactants. Formulations suitable forsubcutaneous injection may also contain additives such as preserving,wetting, emulsifying, and dispensing agents. Prevention of the growth ofmicroorganisms can be ensured by various antibacterial and antifungalagents, such as parabens, chlorobutanol, phenol, sorbic acid, and thelike. It may also be desirable to include isotonic agents, such assugars, sodium chloride, and the like. Prolonged absorption of theinjectable pharmaceutical form can be brought about by the use of agentsdelaying absorption, such as aluminum monostearate and gelatin.

For intravenous injections, compounds described herein may be formulatedin aqueous solutions, preferably in physiologically compatible bufferssuch as Hank's solution, Ringer's solution, or physiological salinebuffer. For transmucosal administration, penetrants appropriate to thebarrier to be permeated are used in the formulation. Such penetrants aregenerally known in the art. For other parenteral injections, appropriateformulations may include aqueous or nonaqueous solutions, preferablywith physiologically compatible buffers or excipients. Such excipientsare generally known in the art.

Parenteral injections may involve bolus injection or continuousinfusion. Formulations for injection may be presented in unit dosageform, e.g., in ampoules or in multi-dose containers, with an addedpreservative. The pharmaceutical composition described herein may be ina form suitable for parenteral injection as a sterile suspensions,solutions or emulsions in oily or aqueous vehicles, and may containformulatory agents such as suspending, stabilizing and/or dispersingagents. Pharmaceutical formulations for parenteral administrationinclude aqueous solutions of the active compounds in water-soluble form.Additionally, suspensions of the active compounds may be prepared asappropriate oily injection suspensions. Suitable lipophilic solvents orvehicles include fatty oils such as sesame oil, or synthetic fatty acidesters, such as ethyl oleate or triglycerides, or liposomes. Aqueousinjection suspensions may contain substances which increase theviscosity of the suspension, such as sodium carboxymethyl cellulose,sorbitol, or dextran. Optionally, the suspension may also containsuitable stabilizers or agents which increase the solubility of thecompounds to allow for the preparation of highly concentrated solutions.Alternatively, the active ingredient may be in powder form forconstitution with a suitable vehicle, e.g., sterile pyrogen-free water,before use.

Other Formulations

Examples of Methods of Dosing and Treatment Regimens

The compounds described herein can be used in the preparation ofmedicaments for the inhibition of Btk or a homolog thereof, or for thetreatment of diseases or conditions that would benefit, at least inpart, from inhibition of Btk or a homolog thereof. In addition, a methodfor treating any of the diseases or conditions described herein in asubject in need of such treatment, involves administration ofpharmaceutical compositions containing at least one compound of any ofFormula (IA), (I), (Ia), (II), (III), (IV), (Va)-(Vh), or (VIa)-(VIb),described herein, or a pharmaceutically acceptable salt,pharmaceutically acceptable N-oxide, pharmaceutically active metabolite,pharmaceutically acceptable prodrug, or pharmaceutically acceptablesolvate thereof, in therapeutically effective amounts to said subject.

The compositions containing the compound(s) described herein can beadministered for prophylactic and/or therapeutic treatments. Intherapeutic applications, the compositions are administered to a patientalready suffering from a disease or condition, in an amount sufficientto cure or at least partially arrest the symptoms of the disease orcondition. Amounts effective for this use will depend on the severityand course of the disease or condition, previous therapy, the patient'shealth status, weight, and response to the drugs, and the judgment ofthe treating physician. It is considered well within the skill of theart for one to determine such therapeutically effective amounts byroutine experimentation (including, but not limited to, a doseescalation clinical trial).

In prophylactic applications, compositions containing the compoundsdescribed herein are administered to a patient susceptible to orotherwise at risk of a particular disease, disorder or condition. Suchan amount is defined to be a “prophylactically effective amount ordose.” In this use, the precise amounts also depend on the patient'sstate of health, weight, and the like. It is considered well within theskill of the art for one to determine such prophylactically effectiveamounts by routine experimentation (e.g., a dose escalation clinicaltrial). When used in a patient, effective amounts for this use willdepend on the severity and course of the disease, disorder or condition,previous therapy, the patient's health status and response to the drugs,and the judgment of the treating physician.

In the case wherein the patient's condition does not improve, upon thedoctor's discretion the administration of the compounds may beadministered chronically, that is, for an extended period of time,including throughout the duration of the patient's life in order toameliorate or otherwise control or limit the symptoms of the patient'sdisease or condition.

In the case wherein the patient's status does improve, upon the doctor'sdiscretion the administration of the compounds may be givencontinuously; alternatively, the dose of drug being administered may betemporarily reduced or temporarily suspended for a certain length oftime (i.e., a “drug holiday”). The length of the drug holiday can varybetween 2 days and 1 year, including by way of example only, 2 days, 3days, 4 days, 5 days, 6 days, 7 days, 10 days, 12 days, 15 days, 20days, 28 days, 35 days, 50 days, 70 days, 100 days, 120 days, 150 days,180 days, 200 days, 250 days, 280 days, 300 days, 320 days, 350 days, or365 days. The dose reduction during a drug holiday may be from 10%-100%,including, by way of example only, 10%, 15%, 20%, 25%, 30%, 35%, 40%,45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, or 100%.

Once improvement of the patient's conditions has occurred, a maintenancedose is administered if necessary. Subsequently, the dosage or thefrequency of administration, or both, can be reduced, as a function ofthe symptoms, to a level at which the improved disease, disorder orcondition is retained. Patients can, however, require intermittenttreatment on a long-term basis upon any recurrence of symptoms.

The amount of a given agent that will correspond to such an amount willvary depending upon factors such as the particular compound, disease orcondition and its severity, the identity (e.g., weight) of the subjector host in need of treatment, but can nevertheless be routinelydetermined in a manner known in the art according to the particularcircumstances surrounding the case, including, e.g., the specific agentbeing administered, the route of administration, the condition beingtreated, and the subject or host being treated. In general, however,doses employed for adult human treatment will typically be in the rangeof 0.02-5000 mg per day, or from about 1-1500 mg per day. The desireddose may conveniently be presented in a single dose or as divided dosesadministered simultaneously (or over a short period of time) or atappropriate intervals, for example as two, three, four or more sub-dosesper day.

The pharmaceutical composition described herein may be in unit dosageforms suitable for single administration of precise dosages. In unitdosage form, the formulation is divided into unit doses containingappropriate quantities of one or more compound. The unit dosage may bein the form of a package containing discrete quantities of theformulation. Non-limiting examples are packaged tablets or capsules, andpowders in vials or ampoules. Aqueous suspension compositions can bepackaged in single-dose non-reclosable containers. Alternatively,multiple-dose reclosable containers can be used, in which case it istypical to include a preservative in the composition. By way of exampleonly, formulations for parenteral injection may be presented in unitdosage form, which include, but are not limited to ampoules, or inmulti-dose containers, with an added preservative.

The foregoing ranges are merely suggestive, as the number of variablesin regard to an individual treatment regime is large, and considerableexcursions from these recommended values are not uncommon Such dosagesmay be altered depending on a number of variables, not limited to theactivity of the compound used, the disease or condition to be treated,the mode of administration, the requirements of the individual subject,the severity of the disease or condition being treated, and the judgmentof the practitioner.

Toxicity and therapeutic efficacy of such therapeutic regimens can bedetermined by standard pharmaceutical procedures in cell cultures orexperimental animals, including, but not limited to, the determinationof the LD₅₀ (the dose lethal to 50% of the population) and the ED₅₀ (thedose therapeutically effective in 50% of the population). The dose ratiobetween the toxic and therapeutic effects is the therapeutic index andit can be expressed as the ratio between LD₅₀ and ED₅₀. Compoundsexhibiting high therapeutic indices are preferred. The data obtainedfrom cell culture assays and animal studies can be used in formulating arange of dosage for use in human. The dosage of such compounds liespreferably within a range of circulating concentrations that include theED₅₀ with minimal toxicity. The dosage may vary within this rangedepending upon the dosage form employed and the route of administrationutilized.

The reversible or irreversible Btk inhibitor compositions describedherein can also be used in combination with other well known therapeuticreagents that are selected for their therapeutic value for the conditionto be treated. In general, the compositions described herein and, inembodiments where combinational therapy is employed, other agents do nothave to be administered in the same pharmaceutical composition, and may,because of different physical and chemical characteristics, have to beadministered by different routes. The determination of the mode ofadministration and the advisability of administration, where possible,in the same pharmaceutical composition, is well within the knowledge ofthe skilled clinician. The initial administration can be made accordingto established protocols known in the art, and then, based upon theobserved effects, the dosage, modes of administration and times ofadministration can be modified by the skilled clinician.

In certain instances, it may be appropriate to administer at least onereversible or irreversible Btk inhibitor compound described herein incombination with another therapeutic agent. By way of example only, ifone of the side effects experienced by a patient upon receiving one ofthe reversible or irreversible Btk inhibitor compounds described hereinis nausea, then it may be appropriate to administer an anti-nausea agentin combination with the initial therapeutic agent. Or, by way of exampleonly, the therapeutic effectiveness of one of the compounds describedherein may be enhanced by administration of an adjuvant (i.e., by itselfthe adjuvant may have minimal therapeutic benefit, but in combinationwith another therapeutic agent, the overall therapeutic benefit to thepatient is enhanced). Or, by way of example only, the benefitexperienced by a patient may be increased by administering one of thecompounds described herein with another therapeutic agent (which alsoincludes a therapeutic regimen) that also has therapeutic benefit. Inany case, regardless of the disease, disorder or condition beingtreated, the overall benefit experienced by the patient may simply beadditive of the two therapeutic agents or the patient may experience asynergistic benefit.

The particular choice of compounds used will depend upon the diagnosisof the attending physicians and their judgment of the condition of thepatient and the appropriate treatment protocol. The compounds may beadministered concurrently (e.g., simultaneously, essentiallysimultaneously or within the same treatment protocol) or sequentially,depending upon the nature of the disease, disorder, or condition, thecondition of the patient, and the actual choice of compounds used. Thedetermination of the order of administration, and the number ofrepetitions of administration of each therapeutic agent during atreatment protocol, is well within the knowledge of the skilledphysician after evaluation of the disease being treated and thecondition of the patient.

It is known to those of skill in the art that therapeutically-effectivedosages can vary when the drugs are used in treatment combinations.Methods for experimentally determining therapeutically-effective dosagesof drugs and other agents for use in combination treatment regimens aredescribed in the literature. For example, the use of metronomic dosing,i.e., providing more frequent, lower doses in order to minimize toxicside effects, has been described extensively in the literatureCombination treatment further includes periodic treatments that startand stop at various times to assist with the clinical management of thepatient.

For combination therapies described herein, dosages of theco-administered compounds will of course vary depending on the type ofco-drug employed, on the specific drug employed, on the disease orcondition being treated and so forth. In addition, when co-administeredwith one or more biologically active agents, the compound providedherein may be administered either simultaneously with the biologicallyactive agent(s), or sequentially. If administered sequentially, theattending physician will decide on the appropriate sequence ofadministering protein in combination with the biologically activeagent(s).

In any case, the multiple therapeutic agents (one of which is a compoundof Formula (IA), (I), (Ia), (II), (III), (IV), (Va)-(Vh), or (VIa)-(VIb)described herein) may be administered in any order or evensimultaneously. If simultaneously, the multiple therapeutic agents maybe provided in a single, unified form, or in multiple forms (by way ofexample only, either as a single pill or as two separate pills). One ofthe therapeutic agents may be given in multiple doses, or both may begiven as multiple doses. If not simultaneous, the timing between themultiple doses may vary from more than zero weeks to less than fourweeks. In addition, the combination methods, compositions andformulations are not to be limited to the use of only two agents; theuse of multiple therapeutic combinations are also envisioned.

It is understood that the dosage regimen to treat, prevent, orameliorate the condition(s) for which relief is sought, can be modifiedin accordance with a variety of factors. These factors include thedisorder from which the subject suffers, as well as the age, weight,sex, diet, and medical condition of the subject. Thus, the dosageregimen actually employed can vary widely and therefore can deviate fromthe dosage regimens set forth herein.

The pharmaceutical agents which make up the combination therapydisclosed herein may be a combined dosage form or in separate dosageforms intended for substantially simultaneous administration. Thepharmaceutical agents that make up the combination therapy may also beadministered sequentially, with either therapeutic compound beingadministered by a regimen calling for two-step administration. Thetwo-step administration regimen may call for sequential administrationof the active agents or spaced-apart administration of the separateactive agents. The time period between the multiple administration stepsmay range from, a few minutes to several hours, depending upon theproperties of each pharmaceutical agent, such as potency, solubility,bioavailability, plasma half-life and kinetic profile of thepharmaceutical agent. Circadian variation of the target moleculeconcentration may also determine the optimal dose interval.

In addition, the compounds described herein also may be used incombination with procedures that may provide additional or synergisticbenefit to the patient. By way of example only, patients are expected tofind therapeutic and/or prophylactic benefit in the methods describedherein, wherein pharmaceutical composition of a compound disclosedherein and/or combinations with other therapeutics are combined withgenetic testing to determine whether that individual is a carrier of amutant gene that is known to be correlated with certain diseases orconditions.

The compounds described herein and combination therapies can beadministered before, during or after the occurrence of a disease orcondition, and the timing of administering the composition containing acompound can vary. Thus, for example, the compounds can be used as aprophylactic and can be administered continuously to subjects with apropensity to develop conditions or diseases in order to prevent theoccurrence of the disease or condition. The compounds and compositionscan be administered to a subject during or as soon as possible after theonset of the symptoms. The administration of the compounds can beinitiated within the first 48 hours of the onset of the symptoms, withinthe first 6 hours of the onset of the symptoms, or within 3 hours of theonset of the symptoms. The initial administration can be via any routepractical, such as, for example, an intravenous injection, a bolusinjection, infusion over 5 minutes to about 5 hours, a pill, a capsule,transdermal patch, buccal delivery, and the like, or combinationthereof. A compound should be administered as soon as is practicableafter the onset of a disease or condition is detected or suspected, andfor a length of time necessary for the treatment of the disease, suchas, for example, from about 1 month to about 3 months. The length oftreatment can vary for each subject, and the length can be determinedusing the known criteria. For example, the compound or a formulationcontaining the compound can be administered for at least 2 weeks,between about 1 month to about 5 years, or from about 1 month to about 3years.

Example 355a Btk In Vitro Inhibitory Activity (Method A)

The Btk IC₅₀s of compounds disclosed herein is determined in both acellular kinase assay and in a cellular functional assay of BCR-inducedcalcium flux as described below.

Btk kinase activity is determined using a time-resolved fluorescenceresonance energy transfer (TR-FRET) methodology. Measurements areperformed in a reaction volume of 50 μL using 96-well assay plates.Kinase enzyme, inhibitor, ATP (at the K_(m) for the kinase), and 1 μMpeptide substrate (Biotin-AVLESEEELYSSARQ-NH₂) are incubated in areaction buffer composed of 20 mM Tris, 50 mM NaCl, MgCl₂ (5-25 mMdepending on the kinase), MnCl₂ (0-10 mM), 1 mM DTT, 0.1 mM EDTA, 0.01%bovine serum albumin, 0.005% Tween-20, and 10% DMSO at pH 7.4 for onehour. The reaction is quenched by the addition of 1.2 equivalents ofEDTA (relative to divalent cation) in 25 μL of 1× Lance buffer(Perkin-Elmer). Streptavidin-APC (Perkin-Elmer) and Eu-labeled p-Tyr100antibody (Perkin-Elmer) in 1× Lance buffer are added in a 25 μL volumeto give final concentrations of 100 nM and 2.5 nM, respectively, and themixture is allowed to incubate for one hour. The TR-FRET signal ismeasured on a multimode plate reader with an excitation wavelength(λ_(Ex)) of 330 nm and detection wavelengths (λ_(Em)) of 615 and 665 nm.Activity is determined by the ratio of the fluorescence at 665 nm tothat at 615 nm. For each compound, enzyme activity is measured atvarious concentrations of compound. Negative control reactions areperformed in the absence of inhibitor in replicates of six, and twono-enzyme controls are used to determine baseline fluorescence levelsInhibition constants, K_(i)(app), were obtained using the programBatchK_(i) (Kuzmic et al. (2000), Anal. Biochem. 286:45-50). IC₅₀s areobtained according to the equation:IC ₅₀ ={Ki(app)/(1+[ATP]/K _(m) ^(ATP))}+[E] _(tota)½;

For all kinases, [ATP]=K_(m) ^(ATP), [Btk]_(tota)1=0.5 nM and[Lck]_(tota)1=6 nM.

Example 355b Btk In Vitro Inhibitory Activity (Method B)

Kinase activity is measured in vitro using electrophoretic mobilityshift assay. The kinase reactions are assembled in a total volume of 25μL in 384 well plates. The reactions comprise: BTK enzyme (1 nM,N-terminal His6-tagged, recombinant, full-length, human BTK purifiedfrom baculovirus Sf21 insect cell system), inhibitor, ATP (16 μM, theapparent K_(m) for the kinase), fluorescently labeled peptide substrate(1 μM, FAM-GEEPLYWSFPAKKK-NH2) in a reaction buffer composed of 100 mMHEPES, pH7.5, 5 mM MgCl₂ 1 mM DTT, 0.1% bovine serum albumin, 0.01%Triton X-100, and 1% DMSO. The reaction is incubated for one hour and isquenched by the addition of 45 μL of termination buffer (100 mM HEPES,pH7.5, 0.01% Triton X-100, 30 mM EDTA). The terminated reactions areanalyzed using 12 channel LabChip® 3000 microfluidic detectioninstrument (Caliper Life Sciences). The enzymatic phosphorylation of thepeptide results in a change in net charge, enabling electrophoreticseparation of product from substrate peptide. As substrate and productpeptides are separated, two peaks of fluorescence are observed. Changein the relative fluorescence intensity of the substrate and productpeaks is the parameter measured, reflecting enzyme activity. In thepresence of an inhibitor, the ratio between product and substrate isaltered: the signal of the product decreases, while the signal of thesubstrate increases.

Activity in each sample is determined as the product to sum ratio (PSR):P/(S+P), where P is the peak height of the product peptide and S is thepeak height of the substrate peptide. For each compound, enzyme activityis measured at various concentrations (12 concentrations of compoundspaced by 3× dilution intervals). Negative control samples(0%-inhibition in the absence of inhibitor) and positive control samples(100%-inhibition, in the presence of 20 mM EDTA) are assembled inreplicates of four and are used to calculate %-inhibition values foreach inhibitor at each concentration. Percent inhibition (P_(inh)) isdetermined using following equation:P _(inh)=(PSR_(0%)−PSR_(inh))/(PSR_(0%)−PSR_(100%))*100,where PSR_(inh) is the product sum ratio in the presence of inhibitor,PSR_(0%) is the average product sum ration in the absence of inhibitorand PSR_(100%) is the average product sum ratio in 100%-inhibitioncontrol samples;

The IC50 values of inhibitors are determined by 4 parameter sigmoidaldose-response model fitting of the inhibition curves (P_(inh) versusinhibitor concentration) using XLfit 4 software.

BTK enzyme (8 nM final in reaction), inhibitor(at requested doses), and 0.2 mg/mL peptide substrate (Poly-Glu-Tyr, 4:1ratio) are incubated in a reaction buffer composed of 20 mM Hepes (pH7.5), 10 mM MgCl₂, 1 mM EGTA, 0.02% Brij35, 0.02 mg/ml BSA, 0.1 mMNa₃VO₄, 2 mM DTT, 1% DMSO for 15 min. followed by addition of 1 μM ATPto start the assay. Kinase reactions are carried out for 120 min. atroom temperature. The reaction was stopped by spotting of reactionsample onto P81 cationic exchange paper (Whatman). Unbound phosphate wasremoved by extensive washing of filters in 0.75% Phosphoric acid. Aftersubtraction of background derived from control reactions containinginactive enzyme (via addition of saturating EDTA), kinase activity datafor each dose of compound tested was expressed as the percent ofremaining kinase activity in test samples compared to vehicle (dimethylsulfoxide) reactions.
